[NANOG] Multihoming for small frys?

I got a /22 in January, and was told by someone from ARIN that the
policy below only applied to allocations to ISP's, not to assignments
for end customers.  At the time, they said an end user must show at
least 25% immediate usage (so a /24) and that there was no requirement
for future usage.  In my experience, if you can show you have some
semblance of ability, two real peers, and an existing and established
business, you should be able to get the request through easily in about
a week, start to finish.  When you're ready, fill out the request form,
the worst that can happen is they reject you or defer you until you can
provide more info.  If you have questions for/about ARIN, call them
(number is on the website) and talk to one of their people, they've been
pretty knowledgeable, friendly, and helpful in my experience.

Thanks for the info.  We needed larger than /22 anyways.

I am a bit surprised that they will hand out a small allocaiton for 
multihomers.  These days it's very easy to do.  And, could be a easy way
to 
horde some v4.

Notice the caveats:

To qualify under the IPv4 Multi-homing policy, your organization must
prove 
an intent to multi-home, demonstrate utilization for at least a
/23-worth of 
IP addresses assigned by upstream providers, and provide 3-, 6-, and 
12-month utilization projections.

In addition, your organization must agree to use the requested IPv4
address 
space to renumber out of your current address space, and to return the 
original address space to your upstream provider(s) once the renumbering
is 
complete. Additional space will not be allocated until this is
completed. 
Organizations that qualify under this policy may also qualify and
request 
space under ARIN's general IPv4 allocation policy.

Of course, this could be smoke and mirrors.  Not sure.
